To all whom it may concern:

Be it known that I, DANIEL HOWARD HAY- woon, a citizen of the United States of.

tiguous thereto, and being carried along thereby in the further operation of the machine as sometimes happens in this class of apparatus. To this end I provide means automatically operated by the breaking of a thread for stopping the further supply of such thread. Thus, if by any chance, a broken thread end becomes entangled with another thread it will be impossible for it to be carried along by and with the said other thread. The thread end will either be Withdrawn from such entanglement by the furtherforward movement of the unbroken thread, or, if the entanglement is such as to prevent the latter thread from being released, the entangled thread will again be broken, or the thread with which it is entangled will itself be brokenand further feed of it prevented. It is better for a second thread to be broken rather than for double threads to be formed, because in the former case it is a simple matter to reconnect a broken thread directly it is noticed by the attendant while in the latter case it would necessitate'unwinding of a more or less large quantity of thread from a spool or other device upon which it is taken up, or the discarding of such a spool or bobbin,

1 or worse than all, if it is unnoticed and the bobbin goes to the silk mills, such double thread will cause serious inconvenience when employed for use in the looms.

The preferred form of my invention comprises individual levers, one for each thread, each said lever held in an upper position by en agement with the thread, but allowed to fall by gravity when the thread breaks and in so falling the said lever is caused to engage a portion of the spool or bobbin sameto a stop.

from which the silk is supplied so as to bring The preventin of further course, to

I also preferably provide means for ho ding the levers in their upper position mechanically and without support of the threads so that the levers are thus held prior to, and in the first starting up of the machine, and between times of operating the machine. This supporting device may conveniently be made common to a number, or indeed, if desired, to all of the bobbins, so that a single movement will be all that is necessary to throw it into, or out of, operative position, a large number of the said levers.

In connection with the means for stopping I thesupply of thread, I may also employ, if desired, a means also operated automatically upon the breaking of a thread for swinging the broken thread end out. of. the path of movement of other threads. In the ordinary arrangement of these threads bobbins are arranged, one above the other, so that when the thread of one bobbin breaks it is likely to fall upon the thread immediately beneath it. Such a device as I have just mentioned may readily consist of a lever pivoted at a point to one side of the thread and engaging same, such lever adapted to swing downward and outward when the thread breaks to carry such thread end away from the thread or threads beneath it. The stop lever may then be supported by such last mentioned device so that the breaking of the thread will. both cause the further feeding of the thread to be impossible, and will also swing aside. the broken end.

In order that my invention may be fully understood, I will now proceed to describe an embodiment thereof, having reference to the accompanying drawings, and will then point out the novel features in claims.

In the drawings: Figure 1 is a view partly in side elevation and partly in vertical longitudinal section ofsuch parts of a silk finishing machine as are necessary for the illustration of my invention. Fig. 2 is a top view thereof. Fig. 3 is a front view of certain parts of the creel employed. showing therein means embodying my invention for arresting the further supply of thread after such thread has been broken. Fig. at is a top view of the same. Fig. 5 is a detail view in vertical transverse section thereof. support, so as to bear but lightly upon the Figs. 6 and 7 are respective front and cross sectional views of a modified construction in -which a means for swinging the broken thread end aside is employed in combination with a means for preventing further thread from being supplied.

The operation of the finishing machine illustrated here comprises a creel 10 for holding the bobbins containing the threads to be treated; a bath 11 in which the threads are to be immersed, and a heated contact table 12 over which the threads are drawn to be heated, ironed andpolished. The threads are drawn over the table 12 by take-up mechanism of any suitable character, not shown. In finishing machines of this character the threads invariably break at some point between the creel 10 and the bath 11; after they have been treated in the bath 11 they are considerably stronger than before such treatment, so that the breakage, if any, occurs before they are received in the bath. The creel comprises a number of bobbins arranged in a frame in vertical andhorizontal rows. In the creel illustrated there are seventy-two bobbins arranged in nine horizontal rows, eight bobbins in each row, or in other words, the bobbins as arranged, comprise a rectangular figure containing eight bobbins inthe horizontal rows and nine in the vertical rows. they are similarly disposed, but they pass thence to a plurality of guides 13 which are in a single horizontal line, the threads being carried thence in .such a line through the bath and over the ironing table.

It will be readily understood that when an upper thread breaks between the creel and. theironing table the tendency is for the broken end to fall upon a thread beneath it, but as a very slight engagement between two silk threads causes sufiicient adherence between them to cause one thread to carry the other with it, the result of this,

- in the past, has been that the broken thread has been picked up by the thread beneath it and carried along through the bath and over the table to the take-up mechanism. It is to prevent this that I have provided means automatically operated by the breaking of thethread for arresting the further supply of the thread, so that once a thread is broken such thread cannot be drawn any further through the apparatus. In the present example of my invention this means comprises a lever 14: for each thread, such lever pivoted to a support 15 conveniently located near the bobbin, the lever being provided with a guiding element 15 for engaging the thread and through which the thread is compelled to pass as it leaves the creel. The tension of the thread sup orts the lever, said' lever being convenient y counterbalanced upon the opposite side of its pivotal In leaving the creelthread, and therefore, to oppose but little frictional resistance to its movement. The lever 14 is provided with a tooth 16, said tooth disposed at a point above a ratchet wheel 17 with which the bobbin is provided. If a thread breaks the lever immediately drops allowing the tooth 16 to engage the ratchet wheel 17 of the bobbin, and thus to prevent further rotation of the bobbin and so to arrest further feeding movement of l the thread. Not only Will the bobbin be thus held so as to prevent rotation thereof should tension be applied to the thread as by its being picked up by another thread, but further, it will prevent rotational movement of the bobbin due to its own momentum when a thread is broken, and this movement alone being a source of considerable trouble, for, owing to the high rate of speed at which these machines are operatedthese bobbins have suficient momentum to unwind a considerable quantity of thread before they come to rest. It will be readily understood how the unwinding of a loose end of thread would tend to largely increase the liability of such thread end to be caught up by other threads. V

For the purpose of holding the levers 14 in their upper position before a machine is started into operation or between the times of its operation, I have provided means comprising abutments 18, which are arranged to be moved to a position to engage the levers 1 1 to so support them, or move it to such position at will. These abutments are conveniently. formed as cranked portions in light transverse shafts or wires 19, which extend across the creel. The end of such shaft or wire may be upturned as shown at 20 in Fig. 1 to form handles by which they may be operated. All of these shafts or wires may be connected together as by means of a link 21, if desired, so that all the abutments may be thrown into, and out of, position by the manipulation on the part of the attendant of a single device.

in Figs. 6 and 7 T have shown in addition to the levers 14: other levers 22 arranged at right angles thereto, being pivoted as at 23 at points to one side of the bobbins. Tn this case the levers 22 may convenientlyparry the guiding member 24, which corresponds to the guiding element 15, of the lever 14; a lever 25, corresponding to the lever 14, except that it does not have the guiding element 15 thereon, being arranged with its end resting upon the lever 22, all as will be clearly understood by reference tothe drawings. The lever 22 may be artially counterbalanced but sufiicient welght left upon the thread side of its point of support, whereby upon the thread becoming broken the said lever will swing downward and outward, whereby to swing the broken thread present invention.

end clear of the threads beneath it." The same operation will cause the lever 25 to drop so as to stop the bobbin. It will be noted that I make no claim herein to the means for swinging the thread aside per 86 as this device per 86 forms no part of the I do claim, however, herein the means automatically operated upon the breaking of the thread for arresting further supply of thethread, and also such means in combination with the means for swinging the broken thread aside.-

In the construction shown in Fig. 7 I have provided a means similar to the means employed for supporting the lever 14, for supporting the lever 22, such means comprising transverse wires or shafts 26 similar to the transverse wires or shafts 19, such wires or shafts provided with abutments 27 which may bemoved to a position to engage the said levers 22 or to such a position that they will be clear thereof.

What I claim is:

1. In a silk thread finishing machine, the combination with means for operating upon a plurality of individual silk filaments and means for supporting a plurality of bobbins which constitute a source of supply of the said filaments, each of the said bobbins being provided with a ratchet wheel, of individual levers pivoted in proximity to the bobbins and which are ada ted to be supported by the filaments, an a counter-balance for counter-balancin the greater portion of the weight of the Iever, whereby the said levers will rest but lightly upon the said filaments, each said lever being provided with a tooth which is adapted to engage the ratchet wheel of its bobbm to lock the bobbin against further movement upon release of tension of the filaments supplied by the bobbin, due to the breakage of the said filament. v
